FIELD: mining.SUBSTANCE: invention relates to mining and can be used for pushing the cable in the borehole. Apparatus comprises a housing mounted in the encapsulation cable, hydraulic actuator and a hydraulic motor. Hydraulic actuator comprises an oil pump, valve, pressure control valve, and the hydraulic oil tank that is used as a hydraulic power source and circulating in a closed system. Hydraulic motor includes a sealed cylindrical housing located therein, and the shutter member covering the cable, located on opposite sides of this element on the upper and lower pistons forming the upper and lower housings of working cavities which are connected to respective channels with a hydraulic actuator. Element for coverage and descent of the cable is designed as a spring-loaded conical metal trunnions or as traction sleeves made of soft elastic material. Between the upper piston and hydraulic component for coverage and lowering of the cable an insert is placed at the bottom of an annular tapered end for mating with conical traction sleeve or trunnions. Upper and lower working chambers are connected to the hydraulic motor in the housing channels with a hydraulic directional control valve drive via high pressure hoses to form a closed oil circulation system.EFFECT: technical result is to increase the reliability of the device.1 cl, 1 dwg |
